DiskIO speed benchmark of Windows Server

Question

_{Sunday, April 28, 2019 6:56 AM}

Hi all,

I want to test the disk read/write speed on Windows Servers (Windows Server 2012 R2 and 2016). Because it's datacenter servers, so it better to use built-in tools rather than external tools. Is there any good tool that I can use?

I have tried WinSat, but the result looks strange for the data is too big and the duration time of testing is too short which only lasts for about only 4 seconds:

> Disk  Random 16.0 Read                       1265.08 MB/s          9.0
> Disk  Sequential 64.0 Read                   2652.19 MB/s          9.2
> Disk  Sequential 64.0 Write                  3146.00 MB/s          8.5
> Disk  Random 16.0 Write                      1063.91 MB/s

I have checked the device manager, and the write cache of the disk is closed, I don't understand which the data is so big. It's a SSD and I cannot find out the disk type for in device manager, it just shows it's LOGICAL DISK instead of the disk type.

Thanks in advance for your help.

Hello,

If you want to get some proper results, I believe third party tools will give you better results.

You can use the builtin Performance Monitor to capture disk I/O activity as well, you can refer to the guide below:

Configuring Windows Performance Monitor to Capture Disk I/O Activity and Potential Disk Issues

For third party tools, here's a few tools:

• Diskspd
• Atto Disk Benchmark

You'll find an excellent testing methodology in this article under section "Configuring testing tools" :
